• The emulator uses the H-UDI; do not access the H-UDI.

• Low-Power States (Sleep and Standby)

For low-power consumption, the SH7618 has sleep and standby states.

The sleep and standby states are switched using the SLEEP instruction. When the emulator is

used, only the sleep state can be cleared with either the normal clearing function or with the [Stop]

button, and a break will occur.

Note: The memory must not be accessed or modified in sleep state.
